AGREEMENT STATE REPORT - SOURCE DISCONNECTED FROM RADIOGRAPHY CAMERA

The following information was received from the State of Minnesota via email:

"Licensee was performing radiography on steam pipes in a bunker under the road (temporary jobsite). The bunker is accessed by two manholes in the street. At approximately 10:40 a.m. on 8/21/08 the licensee had a disconnect. The assistant under the supervision of the radiographer was cranking the source in, but did not feel it lock into place. The radiographer used the survey meter while the assistant cranked in and out. The readings on the survey meter did not change so they knew they had a disconnect and called the RSO.

"The RSO was notified at approximately 11:00 a.m. The RSO and another employee (former RSO) went to the scene. When they arrived onsite the readings at the manhole entrances were 80 mR/hr and 150 mR/hr, a couple of feet to the sides was background. The radiographer had roped off the area around the manhole entrances and the roped area was maintained until the RSO arrived on-site.

"The RSO, former RSO, and radiographer used telescopic poles to manipulate the camera, and guide tube into a position where the could lower bags filled with lead shot to shield the source. They were then able to enter the bunker and use a 'fishing' cable run through the camera and guide tube to grab the source. They exited the bunker and pulled the 'fishing' cable back until the source locked into the camera.

"The RSO and other employee were wearing dosimeters, direct reading dosimeters (DRDs), and alarming rate meters. At the end of the retrieval the RSO and former RSO had reading on there DRDs of 30 - 35 mR each. The radiographer had a reading on his DRD of 25 mR.

"In looking at the pig tail after the incident, the licensee thinks there is a faulty pig tail connection. The connection between the drive cable and pig tail needed to be forced to get connected, but once connected 'felt sloppy.' The licensee contacted the manufacturer and will be returning the source and cables to the manufacturer for investigation."

OFFSITE NOTIFICATION AND PRESS RELEASE DUE TO INADVERTENT AIRING OF A EMERGENCY BROADCAST MESSAGE

"On August 27, 2008 at 0950 CDT, a local radio station (in Clinton, Iowa) mistakenly activated an emergency broadcast message concerning the Quad Cities Station.
